Google removed the num=100 parameter – what it means for SEO

Google removed the num=100 parameter - the setting that allowed users to display 100 search results on a single page – causing significant disruption in the world of SEO. According to an analysis of 319 websites by Tyler Gargula from LOCOMOTIVE Agency, as many as 77% of sites experienced a drop in keyword visibility, and 87.7% a decline in impressions in Google Search Console reports.

Why did Google remove the parameter?

The removal of the &num=100 parameter marks the end of long-standing reporting and ranking practices. For years, SEO specialists could configure 100 results on one page in Google Search, which made it easier to analyze search results and monitor changes. Now that the parameter has been removed, there are clear shifts in how Google Search Console data reports positions and visibility.

Experts, including Brodie Clark and Barry Schwartz, emphasize that previous data may have been distorted by tools and bots using this parameter. In practice, part of earlier Search Console data may not have reflected the actual positions of websites in the search engine.

What are the effects?

• Drop in queries: 77.6% of sites lost unique terms in reports.

• Shorter keywords impacted: short-tail and mid-tail keywords saw the biggest declines.

• Average position: many sites improved their average position, but this is a side effect of no longer inflating results with 100 results at once.

• Visibility and impressions: many specialists report they now need to re-analyze data and adjust their ranking monitoring strategies.

Importantly, the subsequent pages of search results look different today – fewer queries reach page three or beyond, while more concentrate on page one and the top three positions. This means that rankings are now closer to the actual presentation of results, without distortions created by mass queries and scraping.

SEO tools and position tracking

SEO tools, such as Semrush and Accuranker, confirmed disruptions in reporting. Semrush admitted that the change affected the performance of its systems and that adjustments are in progress.

For companies and agencies, this means a shift in how ranking data is monitored. Reports that previously tracked the top 100 search results (or top 50) must now rely on new metrics and limitations.

What’s next for SEO?

It’s still unclear whether this change is permanent or just a test. Google has not issued an official statement, but available data shows the impact on the SEO industry is significant.

Experts stress that while content and link building remain essential, SEO professionals must adapt to new reporting methods. Specialists need to learn to work with fewer data points and better interpret real visibility in Google results.

Some suggest that AI may also play a role in how results are presented and how third-party tools report data going forward.

A broader perspective for the industry

This change clearly shows that Google Search continues to evolve, and features that have been standard for years can disappear overnight. It’s a reminder that the industry cannot rely solely on a single metric or parameter – flexibility and adaptability are essential.

Companies need to invest in SEO tools that better interpret real user behavior, not just technical data. At the same time, the importance of creating high-quality content grows, since valuable resources will remain visible regardless of algorithm or parameter changes.

Key takeaways for SEO specialists

Although the removal of the &num=100 parameter caused disruption, there are also positives. Google Search Console data is now closer to real-world results, and it is no longer possible to artificially expand the number of results on a single page. Reports have become cleaner, and analysis more reliable.

Every data crisis is also an opportunity for growth. SEO professionals now face the challenge of adaptation – embracing new ranking monitoring methods, automation, and the support of artificial intelligence. In the long term, this may bring better outcomes than relying on outdated parameters and technical workarounds.
